This invention relates vto the delivery of sliver from textile machines into cans and in particular to a device for packing such sliver into reciprocating cans.

'15 According to the invention the novel device for packing sliver into reciprocatlng cans consists of two plates disposed above the mouth of the can and swung alternately up and down in phase with the reciprocations of the can so as to press the sliver into the can without interrupting the feed. The effectlve length of each plate-that is to say, the length of plate which makes contact with the sliver on each packing stroke-is preferably '15 half the length of the can, but it may also be greater. The packing device may be actuated by any suitable means and for this purpose the plates are conveniently hinged at one end to a part fixed relatively to the platform carrying the cans and are connected at the other end to a fixed part of the machine through a hinged linkage and in order that filled cans may be removed and replacedby empty ones without disturbing the packlng mechanism the plates may conveniently be hinged at a point above the mouth of the can.

In order that the invention may be thoroughly understood, a form of construction 1n accordance therewith will not be described by way of example with reference to the accompanying drawings, in which Figure 1 is an elevation of a device for packing the sliver delivered from a carding machine into a reciprocated can, and

Figure 2 is an end view of Figure 1.

Figures 3 and 4 are views corresponding to Figures 1 and 2,"illustrating a modification of the invention;

Figures 5 and 6 are respectively a front and a side elevation of a further modification, and

Figures 7 and 8 are respectively a front elevation and plan of yet another modification.

The sliver is delivered from the carding machine through the rollers 1, 2 and is laid in zigzag formation in the can 3 by the oscillated funnel 4:, while the can 3 is reciprocated on its platform 5 by the crank 6 and connecting rod 7.

In Figures 1 and 2 the can 3 is mounted on the platform 5 within an angle iron framework 8, which is fixed to the platform 5 by means of the gussets 9, and therefore, reciprocates with it. The packing of the sliver in the can 3 is performed by two plates 10 and 11. The plate 10 is of the same width as the can 3 and is half as long and is mounted in two carrying arms 12 hinged at the points 13 to the framework 8 and bent as shown in. the drawings. The plate 10 is also hinged to one end of a rod 14., the other end of which is hinged to the standard 15. The plate 11 is of the same shape and dimensions as the plate 10 and is carried ina similar way by the carrying arms 16. The latter are hinged to the framework at the points 17 and the plate 11 is hinged to one end of a rod 18, the other end of which is hinged to an arm 19 fixed to the machine.

In the position shown in the drawings, the crank 6 and connecting rod 7 are at the outer dead centre position and the plate 11 lies horizontally slightly above the mouth of the can 3, while the plate 10 is in a vertical position. As the crank 6 rotates the platform 5, can 3 and framework 8 move to the right and as the outer ends of the rods 14 and 17 are hinged to fixed parts, the plates 10 and 11 are swung, the one anti-clockwise, and the other clockwise, about the hinges 13 and 17 respectively, until when the inner dead centre position is reached the positions of the plates 10 and 11 have been reversedthat is to say, the plate 10 then lies horizontally slightly above the mouth of the can 3 and the plate 11 is in a vertical position. On continued rotation of the crank 6, the direction of movement of the platform 5 is reversed and, of course, the plates 10 and 11 are swung in the opposite senses.

The sliver delivered from the funnel 4 is piled in the can 3 and, being loosely packed, projects beyond the mouth of the can 3. When, therefore, the plates 10 and 11 are swung into their horizontal position they press the sliver down and owing to the positive way in which they are actuated they are able to exert a considerable pressure. In this way the sliver is progressively packed into the can 3 without in any Way interfering with the feed because the plate 10 or 11, which at any instant is nearest to the funnel 4: is in a more or less raised position.

The bars of the framework 8 are higher than the can 3, so that the latter when it is full can be easily withdrawn and be replaced by an empty one and on this account the carrying arms 12 and 16 are bent to the shape shown so that they may descend. relatively near to the mouth of the can 3 and when there assume a horizontal position.

The carrying arms 12 and 16 are steel sections, sothat they have a certain amount of springiness which is, of course, necessary if good packing is to be obtained, especially when the can is absolutely full.

There are, of course, many alternative ways of actuating the packing plates 10 and 11 and some further examples are illustrated in Figures 3-8.

In Figures 3 and 4c, the can 3 is carried on the platform 5 which is reeiprocated as in the previous case. The outer ends of the rods 14 and 18 are pivoted to a horizontal bar 22 supported by the two columns 23 and the outer ends of the carrying arms 12 and 16 are pivoted not to a framework fixed to the platform, but to slide blocks 24. The sliding blocks 24 are formed as lateral projections from two built-up standards 25 fixed one to each side of the platform 5 and between which the can 3 is placed during the filling operation. The sliding blocks project into corresponding slideways 26 formed in two horizontal bars 27 fixed to the columns 23 as clearly seen in Figure 1. As the platform 5 is reciprocated, the slide blocks 24 are, of course, moved in the slideways 26 and the packing plates 10 and 11 are swung up and down in phase with the platform 5.

A further modification is shown in Figures 5 and 6 in which a framework 8 such as is used in the construction shown in Figures 1 and 2 is used but the arms 12 and 16, instead of being pivoted as in those figures, are fixed on rods 28 journalled in the framework 8 and extended backwards beyond it. A gear wheel 29 is fixed to the end of each of these rods 28 which meshes with a horizontal rack 30 carried by the standard 15 and a column 31. The diameter of the wheels 29 is so chosen that the wheel 29 and, therefore, the packing plate 10 or 11 fixed to it is turned through an angle of 90 every half stroke of the platform 5. This arrangement has the advantage that the rods 14 and 18 can be dispensed with and leads to a general simplification of the arrangement above the can.

Figures 7 and 8 are fragmentary views showing respectively in elevation a plan and further example of construction. Here as in Figures 5 and 6, the packing plates 10 and 11 are fixed on rods 28 and the connecting links lt and 18 are dispensed with. Instead of the wheel 29, however, the rods 28 are each provided with a short arm 32 fixed to it and carrying a roller 33 at its free end which engages in a guideway 34 formed in a horizontal bar 35. This bar 35 is carried by the standard 15 and the column 31 and, as seen in the drawings, has upwardly sloping ends SO that when the rollers 33 reach these sloping portions the short arms 32 are caused to swing and thus to bring the packing plates 10 and 11 alternately into and out of the horizontal position.

In all the arrangements described it will be appreciated that the power for actuating the plates need not be derived from the platform 5, but may if desired be derived quite independently, for example, from a separate crank and connecting rod mechanism.

Many other variations are possible in addition to the above and although the invention has been illustrated in its application to an arrangement having a platform carrying a single can, it is equally applicable to arrangements wherein the platform carries more than one can and wherein filled cans are automatically exchanged for empty ones.
